PATH 2. VOLATILE ORGANIC COMPOUNDS (1 POINT)
- Perform a screening test for total volatile organic compounds (TVOC). Use ISO 16000-6, EPA TO-17, or EPA TO-15 to collect and analyze the air sample. Calculate the TVOC value per EN 16516:2017 ; California Department of Public Health Standard Method v1.2 2017, Section 3.9.4 ; or an alternative calculation method, as long as the full method description is included in the test report.
o If the TVOC levels exceed 500 µg/m [3], investigate for potential issues by comparing
the individual VOC levels from the GC/MS results to associated cognizant authority health-based limits. Correct any identified issues and retest if necessary.
- Test for the individual VOCs listed in Table 3 using an allowed test method and demonstrate that the contaminants do not exceed the concentration limits listed in the table. Laboratories that conduct the tests must be accredited under ISO/IEC 17025 for the test methods they use.
